Right is Olympus, of course. OP gave it up by showing EXIF. 151mm FL - only Pana can do this, so he took Pana image and copy-pasted Olympus to the right.

Left image is larger, and it's 45-200mm because Panasonic would have to be set between 144-147mm to produce the same magnification as Olympus at 150mm.

I also own both and in my case they are closer to each other at 150mm and F8 at that distance, would be harder to distinguish.

Pana 45-200mm degrades more with long focus distances, and at longest FL and infinity I found F10 aperture is the best, despite of diffraction. Still, it gives more reach at 200mm.There is also sample variation with these lenses, so YMMV.

BTW, from my copies I can tell that Olympus is clearly better when shorter than 90-100mm, this is also important.
